CONCORD: Asynchronous Sparse Aggregation Boosts Device-Cloud RAG Efficiency Under Document Isolation
A new framework called CONCORD addresses the challenge of document isolation in device-cloud retrieval-augmented generation (RAG). By treating the cloud as an asynchronous evidence source and introducing waiting debt control and certificate-guided minimal supplementation, CONCORD improves end-to-end throughput by 1.66× to 2.15× over baselines while cutting per-token communication by over two orders of magnitude. Experiments on Natural Questions and WikiText-2 demonstrate comparable answer quality and perplexity.
